Why do you need your carrier to like your phone? Do they not mandate interoperability in your country? Are carriers using phone blacklists?
Nothing didn’t bother to support Verizon’s most important 4G band, it’s not blacklisted it just won’t work well outside of major cities.

They usse carrier whitelists , Which is even worse.
I cannot activded a EU acquired Pixel for instance. Verizon no longer needs to carrier unlock phones after 60 days too :}
Theres multiple carrier that will auto disable you sim if you move it and charge you a fee for it too !
